preparation example Construction

[0034] Some embodiments of the present invention disclose a bio-organic fertilizer substrate for sorghum, the preparation method of which comprises: taking 20-65 parts by weight of fly ash and pulverizing to a particle size of 0.02-20mm to obtain fly ash particles; adding After 40-65 parts by weight of vinegar grains, stir evenly to obtain vinegar grains fly ash mixture, measure the pH value, if the pH value is 6-7, then store it for later use, if the pH value is not between 6-7, then take A small amount of vinegar residue fly ash mixture is adjusted to 6-7 with a pH regulator, and after conversion, the pH value of all vinegar residue fly ash mixture is adjusted to 6-7. Optimally, the pH is adjusted to 6.7-7.

[0035] In some embodiments of the present invention, the preparation method of the bio-organic fertilizer matrix for sorghum comprises: taking 20-65 parts by weight of fly ash, pulverizing to a particle size of 0.02-20mm to obtain fly ash particles; adding 40 -65 parts...

Abstract

The invention relates to bio-organic fertilizer matrix for sorghum and a sorghum cultivation method. The bio-organic fertilizer matrix comprises 40 to 65 parts by weight of vinegar residues, 20 to 65parts by weight of coal ash, and 0 to 5 parts by weight of potassium nitrate. The cultivation method comprises the following steps: applying the bio-organic fertilizer matrix as base fertilizer, wherein the application amount is 1600 to 2000 kg / hm<2>; seeding; performing field management; and harvesting. The coal ash, the vinegar residues and the potassium nitrate are mixed according to an appropriate ratio to be made into base fertilizer, so that the secondary utilization of the vinegar residues and coal ash waste which are difficult to naturally degrade can be realized, the nutritional elements in the vinegar residues can be sufficiently utilized, the vinegar residues are used together with the coal ash, so that the soil characteristics can be effectively improved, and the ecological utilization of the vinegar residues and the coal ash can be realized; orange peel powder is added to be used as the base fertilizer, so that the utilization rate of the nutritional elements in the vinegar residues can be greatly increased; and the bio-organic fertilizer is used as the base fertilizer, and when the bio-organic fertilizer is used for cultivating the sorghum, various growth indexes of the sorghum are better than that of the conventional cultivation matrix.

Description

technical field [0001] The invention relates to the technical field of sorghum planting, and more particularly, relates to a bio-organic base fertilizer for sorghum and a cultivation method for sorghum. Background technique [0002] Sorghum (Sorghum bicolor (L.) Moench) is an annual herbaceous plant in the Poaceae family. Sorghum rice is sweet in taste, warm and astringent in nature, harmonizes the stomach and eliminates stagnation, warms the middle and astringent intestines, and mainly treats spleen deficiency and dampness, indigestion and other diseases. Sorghum likes temperature and light. During the growth period, the required temperature is higher than that of corn, and it has certain high temperature resistance characteristics. The suitable temperature for the whole growth period is 20-30°C. [0003] Vinegar grains are industrial organic wastes discharged from the vinegar industry, which contain a large amount of crude fiber, low protein content, and are difficult to ...
